That statement is not true. During the summer, the sun's rays are more direct, not less.

Here's why:

* Earth's Tilt: The Earth is tilted on its axis. During summer in the Northern Hemisphere, the Northern Hemisphere is tilted towards the sun. This means the sun's rays hit the Northern Hemisphere at a more direct angle, similar to shining a flashlight directly at a surface.

* More Sunlight: Direct rays mean more sunlight reaches a given area, leading to warmer temperatures.

* Longer Days: Summer also brings longer days because the Earth is tilted towards the sun. This means more hours of sunlight and further contributes to warmer temperatures.

Therefore, during the summer, the sun's rays are more direct, leading to warmer temperatures and longer days.
